I'll see how the struts work out, then figure out my next step. I am planning to get some better shocks, maybe some Ranchos. I put Bilstiens on it, and that was a big mistake, they are way too soft for this application. I should have known that when they list the same shock for a D1500 1/2 ton as they do for a D3500 1 ton dually.
Also, I am running air bags, and when I put 80 lbs or so in them to get the truck level, they so hard that the bumps in the road are brutal. If I let the air down, the truck sits on the overload springs, and the ride is equally brutal. I think my 20+ year old main leafs are sagged to much. A friend of mine had a similar situation. What he did was remove the overload springs and add 2 long leafs to the main springs. It worked for him, so I might try that as well.
